Investment Casting (Lost Wax) Machines Operator & Technician Training

Offered by Pertecnica Engineering

Investment casting, also known as lost wax casting, is a precision manufacturing process used to produce complex metal components with excellent surface finish and tight dimensional accuracy. The process involves creating wax patterns, forming ceramic shells, melting out the wax, and pouring molten metal into the mold. Investment casting machines and systems include wax injection units, shell building equipment, dewaxing systems, furnaces, and finishing tools.

This process is widely adopted in industries requiring intricate geometries and high-quality finishes with minimal machining. In modern manufacturing, investment casting plays a crucial role in producing high-performance components. This training program focuses on practical, hands-on learning, enabling operators and technicians to understand equipment, manage production stages, and ensure consistent casting quality in real industrial environments.
